An initiative between Cargo marine vessel (MV) Oleander, WHOI and ASU BIOS is contributing to ocean observations and data collection, and offering peer-reviewed data. Since the 1970s, scientific equipment has been mounted on three different container ships operating consecutively on the 鈥淥leander Line,鈥� which runs between New Jersey and Bermuda, resulting in decades of scientific data. The newest MV Oleander came into service in 2019, and is now providing regular water column, sea surface, and atmospheric measurements. The project is a part of WHOI鈥檚 Science RoCs (Research on Commercial Ships) initiative, which aims to equip many more commercial vessels with sensors to measure physical, chemical, and biological characteristics of the ocean along the world鈥檚 major shipping routes.

Scientists have transformed RNA, a biological molecule present in all living cells, into a biosensor that can detect tiny chemicals relevant to human health. Research by Rutgers University-New Brunswick scientists centers on RNA, a nucleic acid that plays a crucial role in most cellular processes. Their work is expected to have applications in the surveillance of environmental chemicals and, ultimately, the diagnosis of critical diseases including neurological and cardiovascular diseases and cancer.

One shoulder has four separate joints, packed with muscles, that allow movement of the arm in eight different major ways, giving the most degrees of freedom of any joint in the body. But the same complexity that allows such motion also presents opportunities for pain when something goes wrong. A Tufts University School of Medicine expert served as the lead author on two new papers about efforts to help coalesce this information and make it easier for everyone to understand what this unique joint requires to stay healthy.
